MANIFOLDING 'DEVICE' William 0. Pi'eifler, Dayton, Ohio, assignor to The Egry Register Company, Dayton, Ohio, a corporation of Ohio Application December 22, 1932, Serial l\lo. 648,365 4 Claims. (01. 197-126) My invention relates to manifolding devices and a method of handling paper sheets and interleaved carbon sheets. a

It is my objectto provide a continuous feed v g of a plurality of strips of paper into a typewriting machine which may be written upon and torn off in given lengths while employing the same carbon sheets between successive lengths of the main paper sheets that are written upon.

10 It is my object to provide a mechanism and method by which the carbon sheets and paper sheets are written upon and move forwardly as the writing operation takes place. until it is completed; then the carbon and paper sheets 1 are moved backwardly by having their rear ends lifted by hand upon release from the platen; thereafter, the carbon sheets are held in their uppermost position while the paper sheets are fed forwardly without the carbons to the tear- 20 off position and are there-tom ofi; whereupon the carbon sheets are released and are moved forwardly with a new-group of paper sheets for another writing operation.

Referring to the drawings: I

Referring to the drawings in detail I is a type- 25 writing machine having a platen 2 and a pressure roller 3 which is releasable in the usual manner by a suitable hand lever. 4 indicates the type face which engages with the paper sheets to write upon them.

v Mounted upon the typewriter and above the typewriter is the attachment of my invention comprising yoke members 5 which are mounted upon the side frame of the typewriter and held in position by the latch members 6. Any form of mounting may be employed that is desired. This attachment comprises side frame members I which are connected at their lower ends by the cross frame member 8 and at their tops by the cross frame member 9. This forms a rectangular frame made of plates or angles. on the top frame member 9 is a pair of spaced brackets 10 carrying the axle H having the guide sheaves i2 over which the strips of paper are fed from the supply of paper on a roll or pack as at I3. Diagonal brace members 14 are connected at their ends by the cross frame members 8 and 9 and intermediate their ends-at I 5.

The side frame members I carry at the top and bottom transverse axles l6 and I1 respec- 5o tively having sprocket wheels .18 carrying the side chains 19. To these side chains is attached .at 20 the side bar 2| which .has bifurcated ends 22 engaging and guided by the side frame members I. This side bar 2| carries a back plateZZa 66 on which is hinged at 23 the frame 24 having the paper aligning and holding pins 25 which are adapted to enter the file punch holes 26 in the paper sheets and. in similar holes ii in the back plate so that the paper sheets are firmly aligned and held so as to cause them to travel with the carriage when actuated by the side chains l9.

Mounted on the face of the back plate 22 over the cross frame slide bar it is a pair of spaced notched studs 28 which carry a plurality of strips 29 having holes till. These strips each carry 2. depending carbon sheet 39 adapted to be interleaved between the paper strips 32, 33, Sid and 35. A spring plate 36 slotted at its ends at 371 is adapted to be mounted in the notches 38 in the pins 28 in order to hold the several sheets in position on the carbon carrier. Thus, while the pins 25 are in the holes 25 and 2?! carbon sheets and paper strips travel together with the slide bar 25. When the pins 25 are removed as indicated in Figure 5 by the lifting of the lever 39 on the pivot do through the thumb piece ii then the paper strips are permitted to move independently of the carbon sheets. To prevent the carbon sheets moving with the paper sheets I have provided on the lever 39 a finger M which extends over the outside of one of the side frame members i beneath it and inside of it so as to project through the hole 43 in the side frame member l and thus interpose'its nose ill in the path of the side bar 2i to-prevent the side bar moving with the chains and to prevent the chains from moving and to prevent the carbon sheets from moving while permitting the paper strips to move over the carbon sheets freely as in the case when it is desired to move the strips through the machine after having been written upon without the carbon sheets to the tear-oil? position where they can be torn ofi.

In order to insure that the chains will move in unison I have provided a cross frame member 55 which is attached to the chains at M5 and is guided by the vertical guide members 41 that are connected to the upper and lower frame members 8 and 9. This insures uniformity of movement of the two chains. This member 45 also acts as a counter weight.

Method of operation The sequence of operations is as follows: Starting with the frame in its uppermost position as in Figure the carbon sheets are interleaved with the'paper strips in their ready-to-write position shown in Figure 12. The pressure roller 3 is engaging the strips and the strips are engaging the platen. The ends of the carbon sheets are indicated at 48 while the ends of the paper strips are indicated at 49 and the file punch holes in the free ends of the sheets formed from the strips are indicated at 50. As the typewriter rides and the platen turns the carbon sheets and paper strips are moved through the machine and the carriage for the carbon sheets and paper strips moves downwardly as indicated in Figure 1 until it finally reaches the position indicated in Figure 12 when the writing operation is completed.

The next problem is to get the carbon sheets from between the papers into a new writing position and to tear off the written sheets from the paper strips without tearing off the carbon sheets. To do this, the operator places his thumb or other finger beneath the bar 2| as at 5| and,

at the same time, releases the pressure roller 3. By lifting on the bar 2| the paper strips and carbon sheets are returned to their initial position. Then the operator presses the lever 39 at M thereby removing the pins 25 from the holes 26 and 2'! and inserts the pin 42 in the hole 33 so as to hold the carriage 2i from downward upon until they come to their tear-0E position. as indicated in Figures 17 and 18 whereupon the tearing-cit operation takes place along the line indicated at 52. Then the lever 39 is released, the pins 25 enter a new set of holes 26 and the carbon sheets and paper strips are fed forwardly to the writing position as heretofore described.

Referring particularly to Figures 6 and 7, it will be noted that the swinging frame 2% is yieldingly held so that the pins 25 are normally in engage ment with the paper strips by reason of the spring 2am. But, if it is desired to completely detach the pins and render the frame 24 inoperative the frame may be thrown over dead center of the pivot 23 and the spring 2M will hold it in that position so that the strips may be adjusted freely without respect to the pins 25. i

It will be understood that I desire to compre= hend within my invention such modifications as may be necessary to adapt it to varying condi= tions and uses.

Having thus fully described my invention, what 1 claim as new and desire to secure by Letters Patent, is:
